CAR-COUPLING.

SPECIFICATION forming part of `Letters Patent No. 419,341, dated January14, 1890.

i v Application filed October 1l, 1889. Serial No. 326|681. (No model.)

l clear, and lexact description.

The object of our invention is to produce a simple, practical, durable,and efficient carcoupling which will couple cars of diderent heightsfrom bumper to track automatically and permit the detachment of coupledcars from the roof or sides of the cars, as may be desired.

With these objects in View our invention consists in certain features ofconstruction and combination of parts, which will bel hereinafterdescribed, andindicated in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a perspective View of the coupling removed from a can Fig. 2is a longitudinal sectional elevation of the coupling in position on thefront portion of a car-frame. Fig. 3 is a front elevation of thecoupling and its operating mechanism in place on the car body or frame,the link being in section taken on the line 2 2 in Fig. 2; and Fig. etisa transverse sectional view of the coupling detached, taken on theline 1 1 in Fig. 2.

A represents the main section of the drawhead or coupling-body. This iscast from metal into form, vand consists, essentially, of an elongatedbar having the larger portion parallel on the sides and level on thebottom face. Near the front end of the section A it is curved downwardlyon the upper surface and Iiared outwardly on each side to widen thethroat a, formed by recessing said end, the bottom wall of which throatis inclined upwardly from the front edge to insure easy en-l fromlongitudinal displacement a couplingl jaw B, as will be hereinafterexplained. l From the seat c' extend the opposite inclines t tithe'forward slope i terminating at the vertical shoulder c and the rearslope at o, where a seat 3 is formed for a spiral spring g anditsguiderod h, which is seated in the seat c3 and extends through a hole inthe jaw. The forward slope t" is divided by a central tongue r.

The coupling-jaw B, previously mentioned, consists of an essentiallyrectangular casting conforming laterally to the Width of the section A,and is provided with a rounded transverse rib e, adapted to the seatt'and forward of said rib with two triangular lugs ofitting into thetriangular recesses formed on the incline i by the tongue r. shoulder cof the lugs c2 the coupling-jaw B has its top and bottom faces straightand parallel to a point b2, and thence to the front terminal the jaw isgiven an upward curve, which corresponds to the downward curvature ofthe section Ain general form, with exception that the side flanges a4arevnot as deep as are the side flanges a on the section A. An integraldraft-hook b is formed on the front end of the coupling-jaw B, andanotch a2 is produced in the opposite ioor of the throat a of thesection A, thus supporting the nose or terminal of the draft-hook whenthe parts are in closed adjustment and in service. This position of thedraw-head members is shown in Fig. 2, with a link J coupled to the same.The tongue-and-groove connection of the jaw and main section of thedraw-head retains these parts from lateral displacement, and to holdthem together while vibration of the jaw on the seat c' is permitted aclamp composed of the plates C and boltsd is adj usted thereon to alignwith the fulcrum-point or rocking bearing z'. This clamp further securesthe parts together laterally as well as vertically. The resilience ofthe spring g will normally retain the jaw and section A in closed adjust- Inent and yield to allow a longitudinal thrusting movement of thecoupling-link J to raise the jaw and interlock the link with thedrafthook b. A longitudinal perforation D is axially produced in thebody of the section Aat its rear end for the reception of adraft-rod D,acushioning-spring D2 being placed on the same to From the terminal IOOsustain shocks received by the draw-head on its front end, the draw-headbeing attached in the usual way to the car-frame timbers.

Across the end of the car, at suitable points above the dead-wood ortransverse frametimber thereof, a rock-shaft G is revolnbly supported`in bracket-boxes m, that are affixed to the car-body, as shown in Fig.3. Said shaft G is provided with crank-arms k, whereby it may be rockedat either side of the car, and at a central point on the shaft arockarin I-I is secured or formed, to which is attached a chain I, thatis also extended downwardly to connect its lower terminal with a ringfn, secured in the outer end of the jaw B. The chain I is prolonged andvertically extended to the roof of the car, (not shown,) and is theresecured in any manner to be convenient for use when the jaw B is to beelevated and the coupling-link J disconnected there` from by such amovement. v

This coupling may be used on cars having bumpers of varying heights fromthe track and will readily couple with ordinary link-and pin couplings.It is claimed to be eiiicient in operation and not expensive tomanufacture.

Having thus described our invention, what We claim as new, and desire tosecure by Letters Patent, is-

1. In a car-coupling, the combination, with a draw-head main sectionhaving a daring throat with a notch in its iioor, of'a couplingjaw thatis seated to rock on the main section and provided with a hook whichengages the recessor notch in the main-section throat, a securing-clampthat holds these parts together, and a spring: placed between their rearends to close the forward ends, substantially as shown and described.

2. In a car-coupling, a draw-head formed of a main or lower sectionhaving its end recessed to form a Haring throat provided with a notch inits inclined bottoln, and an upper section forming a coupling-jawmounted to rock on the lower section and provided with a hook on itsouter end adapted to enter the notch of the bottom of the main sectionand hold the coupling-link in the said main section, substantially asherein shown and described.

3. In a car-coupling, the combination, with a draw-head main sectionhaving a'notch in the floor of its throat and provided with a transverserecess, as i, of a coupling-jaw provided with a hook atits forward endand with a transverse rib, as e, substantially as shown and described.

4. In a car-coupling, the combination, with a draw-head main sectionhaving a notch in the floor of its throat, a transverse recess, andinclines oppositely extending from said rib, of a coupling-jaw having atransverse rib and triangular lugs forward of said rib, a spring'`interposedbetween the .rear end of the jaw and the main section, andthe clamp C, subw stantially as shown and described.
